How to stop rigid body objects from going out of the object when i spin it too fast
You don't mention whether the objects are simply flying out of the top of the blender or whether they are passing through the sides.
Assuming they are passing through the sides when travelling too fast, the problem is likely due to the number of Steps per Second of the simulation being too low. This results in the objects moving from one side of an obstacle to the other without actually interacting with it and the solution is to increase the Steps Per Second in the Rigid Body World settings so that they collide with the surface.
The Steps Per Second can be found within the Rigid Body World properties within the Scene properties panel :
